Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499218, here are decompositions:

  • 79 + 2147499139 = 2147499218
  • 127 + 2147499091 = 2147499218
  • 181 + 2147499037 = 2147499218
  • 307 + 2147498911 = 2147499218
  • 421 + 2147498797 = 2147499218
  • 541 + 2147498677 = 2147499218
  • 769 + 2147498449 = 2147499218
  • 877 + 2147498341 = 2147499218

Showing the first eight; more decompositions exist.
